One of the long-time mantras in the SEO world, both from the perspective of the Search Engines as well as many leading SEO practitioners, is that there is nothing that a competitor can do to harm your rankings. As outlined recently by Barry Schwartz at the Search Engine Roundtable, this discussion has been going on for years. In fact, Google has a specific FAQ page revolving around the subject:
“What can I do if I'm afraid my competitor is harming my ranking in Google?”
There's almost nothing a competitor can do to harm your ranking or have your site removed from our index. If you're concerned about another site linking to yours, we suggest contacting the webmaster of the site in question. Google aggregates and organizes information published on the web; we don't control the content of these pages.
According to a recent article at Forbes, The Saboteurs of Search, there are in fact some organizations which claim to be able to damage the rankings of a competitor. The article focuses on tactics outlined by one U.K. SEO, Brendon Scott, who actually owns a blog called “SEO Assassin.” The tactics involve off-page SEO techniques that can be used to help a website - primarily focused on link-building - being used to help to create “bad links” to a competitor. This helps to devalue the site from the point of view of a search engine algorithm that relies on inbound links to a website to help it determine the “trust” the community has in a particular site.
One respected SEO has commented at Search Engine Roundtable, saying that many in the industry have blindly believed Google over the years in regards to this idea that one cannot do damage to a competitor’s site. In fact, he relates it to an ostrich hiding its head in the sand:
“Sorry to come over as a bit of a spoilsport but there's a blatant mix of naiveté and faulty logic that's been dominating this discourse for years… Guess what will happen if your squeaky clean organic site on toddler apparel suddenly gets hit with tens of thousands of links coming from domains of the "(edited-out name of ED drug)- (Edited out name of male body part)-enlargement-cheap-cheap-cheap-non-prescription-drugs.info" ilk? Tons of them? Each and every day, sustained over say 3 to 4 weeks?”
The AA | RF SEO team will monitor for any such tactics occurring by keeping track of inbound links to a client’s site or sites. The team will not engage in any tactics to try and harm competitor rankings – instead focusing on only “white hat” search engine-approved SEO best practices.
